Stupid question, and maybe I'm just obsessing way too much, but I'm not sure where to find a good answer. Is it preferable to run 2 seperate vacuum lines into the car for boost gauge and MS map sensor, or is it fine to just T the line once it's in the car so it reads both sources? How do you guys have your car setup?

 

T it all, just make sure the main source is off of the stock FPR line.
